I've yet to have a computer that was made in the past 5 years that I haven't been able to get it running on. It's amazing.
If you start it with the non-free (as in libre) installer, you'll definitely get near perfect hardware support. You'll need to install two packages if you want good battery life (TLP and thermald).
After that, it's ready for production use on almost every system I've tried.
If you like it/try it I'd like to see how it works out for you so try and contact me and tell me how it went. I might try starting to recommend this for some family I know who get viruses but don't do much else but Youtube and Facebook.
I have a rule of thumb: I try to NEVER touch the console for my non-development OS. Manjaro allows me to accomplish that and it also works on most hardware I've tested it on.
There is a reason GUIs won out over terminals, and that is because no one in the main stream wants to touch one.
A good OS should allow you to do every necessary task via a GUI. If there is a Linux DE/WM that can provide an experience like that, I feel like GNU/Linux will have its break through in the consumer market.
I use my "I never need to do something in the terminal" as a basic user acceptance test.
